A Research on Usable Cryptographic Protocol and its security model

点击翻译按钮获取中文摘要

In this research, we build authenticated key agreement protocol which is used to establish secure channel on resource constrained devices. This protocol can be performed on the devices which have small computational capabilities and tiny user interfaces. We also establish a security evaluation model for these devices including the specifications of these devices. Then we prove the security of the proposed authenticated key agreement protocol in the model. We also implement basic protocol on the iOS tablet and confirm feasibility of the proposed protocol.
